The human-driven loss of biodiversity has numerous ecological, social, and economic impacts at the local and global levels, threatening important ecological functions and jeopardizing human well-being. In this perspective, we present an overview of how tropical defaunation—defined as the disappearance of fauna as a result of anthropogenic drivers such as hunting and habitat alteration in tropical
The paper considers multi-hop wireless mesh networks that serve multicast periodic packet traffic. The packets from each packet stream are generated at the stream's source node and traverse a number of wireless nodes in order to reach their multiple destination nodes. Packet periodicity means that a common repeatable frame of time slots is defined and that the packets to be transmitted arrive at t
Abstract: A measurement of the cross section for the inclusive production of isolated prompt photons in proton-proton collisions at a centre-of-mass energy of s=8 TeV is presented. The measurement covers the pseudorapidity ranges |ηγ | < 1.37 and 1.56 ≤ |ηγ | < 2.37 in the transverse energy range 25 < ET γ < 1500 GeV. The results are based on an integrated luminosity of 20.2 fb−1, recorded by the

Each author has been involved in every part of the process. Background: In a time when everything is available at
Syftet med studien var att utifrån en kvalitativ ansats undersöka högstadielärares motivation i deras dagliga arbete. I undersökningen har lärarna fått reflektera och berätta om sin självupplevda motivation, hur de upplever sina arbetsuppgifter och hur deras yrke påverkar dem personligen. Undersökningen har gett en djup bild av lärarnas egna upplevelser av sin arbetssituation. Genom semistrukturerThe purpose of this study was to examine motivation of high school teachers in their daily work. The teachers in the study have been given an opportunity to reflect and describe their work motivation, how they experience their work and how their profession affects them personally. The survey has given a deep picture of the teachers' own experiences of their work situation. Through semi-structu
I en teoretisk studie har användbarheten av thermosyphoner för att förbättra säkerheten och effektiviseringen av kemiska reaktorer. Thermosyphoner är en simpel form av en ”heat pipe”, ett ihåligt och slutet rör som är delvis fyllt av en fluid. Om röret värms upp till fluidens kokpunkt inleds en inre fasomvandling vilket används för att förbättra rörets värmeledningsförmåga. Tre simuleringsmodellerIn a theoretical study the use of thermosyphons to improve the safety and efficiency of chem-ical reactors have been evaluated. Thermosyphons is a simple form of a “heat pipe”, a hollow and closed tube that’s partially filled with a fluid. When the pipe is heated up to the boiling temperature of the fluid within a phase change is initiated. The phase-change is used to im-prove the thermal conducti
Offentlig upphandling används som ett sätt för EU att uppnå målet med en inre marknad. Inom denna inre marknad är det viktigt att det råder en fri konkurrens mellan medlemsstaterna. Medlemsstaterna ska aktivt arbeta för att motverka inskränkningar av den fria rörligheten inom marknaden. Det finns flera lagar i Sverige rörande offentlig upphandling som bygger på olika EU-direktiv. Vilken lag soPublic procurement is used as a means for the EU to achieve the goal of a single market. Within this single market, there must be free competition between Member States. Member States shall actively work to counter restrictions to free movement within the market. In Sweden, there are several laws regarding public procurement that are based on EU directives. Which law is to be applied depends
The purpose of this study was to examine the controversy surrounding the Swedish methadone assisted rehabilitation program over time. Which course has the Swedish methadone assisted rehabilitation program, and the controversy surrounding it, taken since the start? Which arguments have been for and which have been against a methadone assisted rehabilitation program in Sweden, and what are these arg
This Master's thesis concerns the classification of compact discs according to the Swedish classification system, SAB. The purpose of this thesis is to critically study and discuss category Y of the SAB-system and its application in Swedish public libraries. The classification system has undergone great changes from the first edition in 1921 until today. In 1921 there were no musical recording
When discussing local development attention is often given to the problems involved. Factors like decreasing population and inadequate infrastructure are two examples. Local politics has, however, lately been argued to have possibilities to affect its own development and its chances to achieve growth. Some of the most important factors from this debate are to make a community attractive for people
Research aim and questions: The aim of this research is to investigate the way Radio Free Europe’s Romanian Language Service presented the events of December 1989 in Romania. Since Radio Free Europe/Radio Liberty was one of the most important international broadcasting institutions during the Cold War, it is relevant to see what kind of interpretation was assigned to Romania’s 1989 political and
En produkts formgivning är avgörande för hur eftertraktad den blir på marknaden, något som resulterat i att stora resurser läggs ner på att ge pro-dukter ett så tilltalande yttre som möjligt. För att investerade resurser inte ska gå om intet är det viktigt att skydda formgivningen på ett adekvat sätt, vilket t.ex. kan göras med hjälp av olika, till viss del överlappande, im-materialrättsliga skyddA product's design is crucial to how popular it will become on the market. This has resulted in that significant resources are laid down to give products an exterior as attractive as possible. To make sure that the spent resources should not be wrecked, it is important to protect the design adequately. This can e.g. be done by different, partially overlapping, kinds of intellectual property pr
I 24 kap. 10 § a-e IL regleras begränsningen i avdragsrätten för ränta på vissa koncerninterna skulder. Reglerna framarbetades i samband med de av Skatteverkets konstaterade skatteflyktsförfaranden som skedde i anslutning till avdrag för koncerninterna ränteutgifter. Skatteverket har försökt att komma åt transaktionerna genom att tillämpa skatteflyktslagen men har inte haft framgång eftersom skattThe Income Tax Act Chapter 24 Section 10 a-e deals with restrictions of interest deductions for certain dividends. The regulations were worked out in connection with the established tax evasion procedures that occurred together with deductions for intergroup interest expenses. The Swedish Tax Agency has attempted to get hold of the transactions by applying the Law Against Tax Evasion, but have not
Men’s violence against women was for a long time considered a private family matter, but is today defined as a widely spread social problem. Researchers, activists and professionals may differ in details about the problem but agrees on one major point; education is the greatest weapon in fighting it. All the professional groups that on some point come in contact with women and men who live in viol
The objective of this study is to reach a better understanding of accidents on Swedish roads involving tractors and to suggest ways of preventing them. In an earlier study we analyzed police-reported fatal accidents and accidents that led to physical injuries from 1992 to 2005. During each year of this period, tractors were involved in 128 traffic accidents on average, an average of 7 people were
This paper presents class-D CMOS oscillators capable of an excellent phase noise performance from a very low power supply voltage. Starting from the recognition of the time-variant nature of the class-D LC tank, accurate expressions of the oscillation frequency, oscillation amplitude, current consumption, phase noise, and figure-of-merit (FoM) have been derived. Compared with the commonly used cla
